Making radio wave pathways smoother. Nittobo’s low-Dk glass cloth revolutionizes the permeability of increasingly sophisticated communication and radar equipment.

Nittobo's "Low-Dk Glass Cloth" is a product made from specialized glass fibers with a lower dielectric constant (Dk) and dissipation factor (Df) compared to conventional E-glass. In modern communication and radar technologies, the radio wave permeability of components is crucial. By using this product as a reinforcing material for FRP (Fiber Reinforced Plastics), it is possible to significantly enhance the radio wave permeability of communication-related components, such as radomes.A key feature of this material is its ability to maintain processability and mechanical properties nearly identical to those of standard E-glass cloth, while providing superior electrical characteristics. It also shows excellent compatibility with various resins, including epoxy and cyanate ester resins, allowing for integration using existing molding processes. This high-performance material offers a new solution for demanding environments—such as next-generation high-speed communications and the aerospace industry—where both precise signal transmission and high structural strength are required.

Proprietary dot coating transforms the common sense of glass cloth. Suppressing fraying and weave misalignment to achieve both dramatic efficiency in layering processes and high-quality results.

Nittobo’s "Glass Cloth Dot" is an innovative new material featuring a uniform dot-pattern coating of hot-melt resin on the surface of glass cloth. It significantly suppresses "fraying," "weave misalignment," and the generation of "glass fuzz (dust)" during cutting and processing—common challenges with conventional glass cloth. This reduces the burden on operators and contributes to maintaining a clean working environment. The most significant feature is its self-adhesive function via heating. This prevents shifting during the layering process and makes shaping to the mold easier, strongly supporting shorter working times and labor savings. The amount and spacing of the hot-melt material can be optimally adjusted according to the application. This ensures product quality stability and improved impact resistance without compromising resin impregnation. It provides the ideal solution for modern composite molding sites where productivity improvements and advanced quality are required.

Infinite possibilities realized through coating - Supporting the resolution of functionalization challenges - Ideal processing for reuse planning.

D-ALIGN is a post-processing technology that coats functional agents in dot form. By applying the coating in a dot shape, it offers the following benefits: 1) It enables functionalization on thin, coarse fabrics and substrates that are difficult to treat. 2) It allows for the easy expression of performance by adhering many functional agents to the surface of the substrate. 3) It enables management of the amount of functional agent adhered, allowing for stable product supply. 4) It is an environmentally considerate process that minimizes chemical waste after processing by using an appropriate amount of solution. 5) It maintains the characteristics of the substrate (such as stretchability and breathability) even after processing. 6) It has effects that prevent fraying and suppress fuzzing of the substrate, contributing to increased work efficiency. This processing technology is suitable for materials under consideration for differentiation and those that are stagnant, leading to the birth of new materials through D-ALIGN processing. It is a recommended processing method for those considering material development.

Combining unbreakable toughness with crystal-clear beauty in a single sheet. Refractive index control rewrites the common sense of transparent resins and glass fibers.

Nittobo’s Glass Fiber Reinforced Transparent Material (developmental product) is a next-generation composite that fuses the structural strength of glass fiber with the superior light transmittance of transparent resin. Conventional FRP (Fiber Reinforced Plastics) faced the challenge of becoming opaque due to light reflecting at the interface where the refractive indices of the resin and glass fiber differ. This product achieves unprecedented levels of transparency by utilizing precision control technology to match the refractive indices of both materials to the limit, thereby suppressing interface reflection. The greatest advantage lies in simultaneously overcoming the lack of strength in transparent plastics and the brittleness/fragility of tempered glass. While being lightweight, it possesses high rigidity and "toughness" that prevents shattering upon impact, making it suitable for structural components where safety is paramount. This high-performance material resolves the design dilemma of requiring light transmission without compromising strength, expanding possibilities as a tough, lightweight alternative to glass and acrylic.

Enabling new design expressions that leverage the inherent beauty of glass cloth weave patterns.

Nittobo’s "GFRP with Visible Weave" is an entirely new decorative composite material developed by precisely adjusting the refractive indices of glass fibers (GF) and the matrix resin. Its greatest feature lies in achieving a sense of transparency and the natural luster of the fibers themselves—a combination previously difficult to balance in conventional FRP. The fiber bundles encapsulated within the resin strongly scatter and reflect light, causing them to appear brilliant. After molding, the glass cloth's weave pattern emerges as a three-dimensional texture, creating a deep 3D effect as if the pattern is floating deep within the resin. While enabling new design expressions that highlight the original beauty of the weave, this next-generation material also firmly maintains the electrical insulation and radio wave permeability inherent to GFRP. It adds transparency and a high-end aesthetic to products without compromising functionality.

Combining the toughness of glass fiber and the moldability of resin in a single sheet. Nittobo’s "Commingled Cloth" enables one-shot molding of complex shapes and dramatic productivity improvements.

Nittobo’s "Commingled Glass Cloth" is an innovative composite material created by twisting and weaving high-strength "glass fibers" with thermoplastic "organic fibers (plastic fibers)" using proprietary technology. Its greatest feature lies in "one-shot molding," which allows products to be manufactured using only heat and pressure. Since the resin is already uniformly mixed with the fibers, the material exhibits exceptional mold-following capability and impregnation. This allows for the precise molding of deep-drawn shapes and complex contours—previously difficult to achieve—in a single process. Consequently, it strongly supports a dramatic shortening of manufacturing steps, cost reduction, and labor savings. Furthermore, by leveraging the properties of thermoplastic resin, post-molding reprocessing and recycling are made easy, contributing to a reduced environmental footprint. While lightweight, it possesses high reaction force and superior impact resistance that surpass aluminum, providing a new standard for manufacturing sites where both strength and productivity are required.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.
